i386: hvf: Drop fetch_rip from HVFX86EmulatorState

Browse source 
The field is used to print address of instructions that have no parser
in decode_invalid(). RIP from VMCS is saved into fetch_rip before
decoding starts but it's also saved into env->eip in load_regs().
Therefore env->eip can be used instead of fetch_rip.

While at it, correct address printed in decode_invalid(). It prints an
address before the unknown instruction.
